and incubation was far advanced, when the storms and winds came. The cradle indeed did rock. The boughs did not break, but they swayed and separated as you would part your two interlocked hands. The ground of the little valley fairly gave way, the nest tilted over till its contents fell into the chasm. It was like an earthquake that destroys a hamlet. No born tree-builder would have placed its nest in such a situation. Birds that build at the end of the branch, like the oriole, tie the nest fast; others, like the robin, build against the main trunk; still others build securely in the fork. The sparrow, in her ignorance, rested her house upon the spray of two branches, and when the tempest came the branches parted company and the nest was engulfed. Another sparrow friend of mine met with a curious mishap the past season. It was the little social sparrow, or chippie. She built her nest on the arm of a grapevine in the vineyard, a favorite place with chippie. It had a fine canopy of leaves, and was firmly and securely placed. Just above it hung a bunch of young grapes, which in the warm July days grew very rapidly. The little bird had not foreseen the calamity that threatened her. The grapes grew down into her nest and completely filled it, so that, when I put my hand in, there were the eggs sat upon by the grapes. The bird was crowded out, and had perforce abandoned her nest, ejected by a bunch of grapes. How long she held her ground I do not know; probably till the fruit began to press heavily upon her.
